2013 R-Spec Sedan charging system problem

[Jeepozeen]

Hello, my battery warning light just started lighting up. I installed a new battery about 3 months ago with no problems until yesterday. Engine started up just fine but then the Battery Discharge Warning chimed in and dash warning light is constant.
I have checked the battery terminals and connections and corresponding fuses in the trunk. The 200amp Alternator fuse in the engine compartment is good. Drive belt is in good condition and tensioned properly.
Is there a control module, fuse or fusable link that I have overlooked? Thank you!

Have you checked the voltage at your battery and alternator yet?

Classic telltale of a failing Alternator.

Needs an alternator most likely. Just replaced mine for same symptoms.

Thanks. On that next.

Put a volt meter on the battery while idling. Should be about 13.5~13.8 or so. If you get 12v or less, it’s alternator replacement time.
